China-Mexico relations have enjoyed sound development since the two countries established diplomatic ties 41 years ago, Zeng said in an interview with Xinhua.

The two sides have carried out comprehensive and in-depth cooperation in politics, trade, culture, education and other fields, he said, citing in particular the frequent exchanges of top-level visits.

In the political field, the two countries forged a strategic partnership in 2003, created a permanent binational commission in 2004, established a strategic dialogue mechanism in 2008, and formed a parliamentary forum in 2010.

"China and Mexico are both important developing countries and emerging-market economies. They hold similar political positions, face similar political circumstances, have many common grounds, and deal with common problems," he noted.

In economic and trade cooperation, China has become Mexico's second largest trading partner, while Mexico is China's second largest in Latin America. Bilateral trade had skyrocketed from 12.99 million U.S. dollars in 1972 to 36.68 billion dollars in 2012.

Pointing out that the areas where the two countries compete only account for a very small part of their foreign trade, Zeng said bilateral trade in general is mutually complementary and beneficial.
